+## How to use this control in your solutions
+
+- Check that you installed the `@pnp/spfx-controls-react` dependency. Check out the [getting started](../../#getting-started) page for more information about installing the dependency.
+- Import the following modules to your component:
+
+```TypeScript
+import { HoverReactionsBar } from '@pnp/spfx-controls-react/lib/HoverReactionsBar';
+```
+
+- Use the `HoverReactionsBar` control in your code as follows:
+
+```TypeScript
+<HoverReactionsBar
+  isOpen={isOpenHoverReactionBar}
+  onSelect={onSelectEmoji}
+  onDismiss={(): void => {
+    setIsOpenHoverReactionBar(false);
+  }}
+  target={divRefAddReaction.current as HTMLDivElement}
+/>
+```
+
+- With the `onSelect` property you can get the selected emoji:
+
+```typescript
+   const onSelectEmoji = React.useCallback(async (emoji: string, emojiInfo: IEmojiInfo) => {
+    console.log('emoji', emoji);
+    console.log('emojiInfo object',emojiInfo);
+    setIsOpenHoverReactionBar(false);
+  }, []);
+
+```
+onSelect: (emoji: string | undefined, emojiInfo?: IEmojiInfo) => void;
+  isOpen: boolean;
+  onDismiss: () => void;
+  top4Reactions?: string[];
+  target: HTMLDivElement;
+  themeV8?: Theme ;
